Be it known that l,(i..\iii: \'ei: l l. llowann, a eitizeii ot' theUnited States, residing at St. Louis, in the State of .dissouri, hare invented a new and useful liiiprovemeiit iii (Jar-l ntlerlrames, ol' whiehthe following is a speeilieation.

My invention rel ol-iss of ear-unlerframe having middle longitudiiialsills and side members or girders without intermediate longitudinalsills, and is in the nature of an improvement on the eonstruetiondeseribed in the Letters Patent of the United States granted to (lareneeH. flown-1rd and (.leorge U. Floyd on January 3, 1905, No. 778,973, foran improvement. in railroad-ears, havin e also in view the eonstriietion described in the patent to (.larenee H. Howard, datedNovember S, ltltl-l, No. 774,474, for improvement in railroad-ears.

My invention has for its object to provide no oi this class with ametallie end li'atiie or casting whieli is adapted to be fixed to andsupported b v the end portion-s of the said sills and members in suehmanner as to prevent its ()\'t.t'll21lilllg end part, when subjected toend strain, from bueltling and at the same time insure the transniissionof the said strain direettv to the ends of the said sills.

it eonsists in features of novelty, as hereinafter described andclaimed, reference being had to the aeeoinpanyiii drawings, forming partof this speeilieation, \vhereoii Figure l is a to i plan viei'v of myimproved metallic and frame for a ear-underl'ranie oi" the classdescribed; Fig, 2, a vei'tieal longitudinal section thereof on line inFig. 1; Figs. 3 and 4, vertieal"transverse seetions through the endframe on lines 3 3 and 4 4, respectively, in Fig. 1; and Fig. 5, an endView thereof.

Like letters and numerals of reference denote like parts in all thefigures.

(1 represents a rectangular-shit )ed frame which is composed,preferably, 0 east-steel integral throughout and adapted to be fixed tothe end portions of the middle longitudinal sills 1 and side members orgirders 2 (which in the present case are respectivel metallic) ofthecar-underfrmne in the same horizontal plane therewith, the frame (reorresponiline 1n outline in top plan to the. end portion 01'' thecar-body.

It is adapted to ion n the bo ly-botster of the car, a

Furthermore, the frame a is secured to the sidemembers or girders; of the underframe by rivets 12, vhich passtherethrough and through the ends 01 the transverse membersB 3 and sidemembers 4 of the frame af the side members in the present case,terminating at the inner transverse member 3 of the bolster b, as shown.

By the above construction it is to be par ticularly noted that the endportions of the middle longitudinal silis 1 insteadiof extending only tothe transverse beam 3, adjacent to the inner end. of the frame andforming the body-bolster in the said patent to Iloward and Floyd, andconsequently leaving the overhanging part oi the frame unsupported,extend in the present case entirely through the bolster approximately tothe outer end of the-frame and is riveted to the latter at suitableintervals longitudinally, whereby the overhanging part of the frame (L'is sup- I portedand prevented from buckling when claim to the use of anintegral castmetal i'rame for connecting the longitudinal memsubjectedto abnormal end strain.

It is to be understood that I make no bers of a car-unde'rframetogether, as I am aware that, the principle is anticipated by the saidpatents/{but That Mo claim as my invention, and desire to secure byLetters Patent, is-- a car-underframe of the class described,
